TOOL FOR EMBOSSING BACKS 0F BOOKS.

i Specification of Letters Patent No. `7,911, dated January 21, 1851. i

T0 all whom it may concern Be it known that I, CHARLES STARR, of thecity, county, andState of New York, have invented a new anduseful'Improvement in Tools for Embossing, Lettering, and Gilding orotherwise Performing what is Technically Termed Finishing Books AfterBinding; and I dohereby declare that the following is a full, clear, andeXact description of the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1, is aperspective view. Fig. 2, is a transverse section` of the tools mounted:on the roller; Fig. 3 is a longitudinal section of the same. F ig. 4, isa transverse section of the outside case detached.

Similar letters `of reference indicate corresponding parts in each ofthe several The nature of my invention relates to the circular orcylindrical tools used by book binders for embossing, lettering andgilding covers ofbooks more especially their backs. b

It consists in theemployment `of a looseihollow cylinder or cylindersfitted upon a solid cylinder or` roller and having spaces. out throughto admit of loose tools being se- "ciired to the solid or foundationcylinder or roller; the edge of the space in the outside cylinderforming the frame margin or outline of the panel or ornament and theinside being iilled with ornaments of any design suitable to thetasteofthe designer or binder.

To enable others" skilled inthe art, to make and use my invention I willproceed to den scribe fully its constructionand operation.

A represents the foundation roller or cylinder which is of metalprovidedwith a hole @,which fits to ashaftor aXle. Bis a case or hollowcylinder which fits to the outside of the cylinder` B, this case or.cylinder being of the requiredfdiameter of the embossing lettering orgilding tool. An opening b, b, of any suitable form is cut through thecase B, the edges ormargin being of any suitable form; in "the drawingit is represented as the frame or border of a panel for the back of abook.` `The space within the openings is illedor partly lled with smalltools (c) `(c) (c) which are secured as is also the case by glue orother adhesive materia-l to the face of the roller A, each tool havingthe same form asthoughit were part of the case or cylinder B, and if itis of the same thickness as the case or cylinder; it is better howeverto glue a piece of paper (d) to the surface of the roller and glue thesmall tools c, c, o, to it as they will hold more securely; `in thelatter case the tools must be as much thinner than the case as thethickness ofthe paper. The tool when b thus prepared isiised in the samemanner as a solid cylindrical tool either in my improved machine forbacking and back-finishing or in any other way that may be convenient.Any number of short cases or cylinders B may be employed upon onefoundation roller A, and letters, figuresor any suitable devicerepresented by or secured within spaces cut in each.

The principal advantage of this improveglued immediately to the rollerA, `must be v ment in the manner of forming the tools consists in t-hegreat number of devices which may be formed by a small number of tools.

I do not claim forming various devices by gliiing or securing loose ordetached too-ls to a surface as'that is common. But

i 1 What I do claim as my invent-ion and desire to secure byLettersPatent, is-

Forming circular embossing gilding or `lettering tools ofany requiredpattern for embossing gilding and lettering book covers `by having acase or hollow metal cylinder B,"`

litt-ing on a roller A, and having an opening b, or `openings in it ofany required form for a panel or other border, the part of the periphery`of the roller A, within the opening or openings in the `case having anyrequired number of small tools a, c, c, of an suitable form o-r patternsecured to it, the surfaces of the said tools standing even with theouter face of the caseor cylinder B, or by the employment of any numberoftools `consisting `of parts of a hollow cylinder ser cured to asolidcylinder substantially o 0 in'the manner herein described.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses this fourth day of January 1851.

` CHARLES STARR.
